TYPE SECTOR...

. Application filed June 30, 1925. Serial No. 40,603. Y

The present invention relates 'to type carrying sectors for printing'1nechan1sms, such for example as operate through the use ot perforated cards as in printing tabulating More specifically the invention relates to a novel alphabetical type sector for positioning the typein printing position in accordance with perforations in a card representing the letter or letters of the alphabet to be printed. r

Some of the objects of the present invention are to provide an improved type carrying sector for printing tabulator's or any other machines wherein a unit of th1s character may be applicable; to provide a control for a type sector whereby a maximum A number of type are carried by the sector and brought to, printing position with a minimum of sector movement; to provide a type sector control whereby type representing all the letters of the alphabet can be set in printing position respectively by twelve control stops; to provide a type sector control consisting of a relatively small number of control members for positioning a relatively large number of type; to provide a type sector control whereby one set of sector control members can be employed to pos1 tion two groups of type, both groups together forming a complete alphabet; andto provide other improvements as willher'emafter appear.

lln the accompanying drawings Fig. 1 represents a side elevation of a type sector control embodying one form of the present invention; and Fig. 2 represents a detail in end elevation of the sector latch mechanism.

Referring to the drawings, one form of the present invention comprls'es a type seetor 10 pivoted to a fixed pivot 11 and carrying a plurality of type 12 whrchareto be brought into operative relation with a platen 13 about which the paper to rece ve the impression passes as Wlll be understood. The type printing takes place by the operation of a pivoted hammer 14 striking the positioned type when the hammer latch 15 is released to permit the hammer spring 16 to come into action. The latch 15 is setfor releasing by a pivoted Iatchpper'ating bar 17 which is arranged to be shifted toset position by the rocking movement of a pivoted bell crank 18', the long arm of which extends into the path of a cam 20 on the sector 10. The hammer release and restoring mechanism comprises a bail 19, a crank arm 21, a shaft 22 on which the bail and crank are fastened, and a retractor link 23, which latter connects to an arm 24 fast to the shaft 25 and which also carries one end of a link 26. The other end of the link 26 is pivoted to an arm 27 which has a rod 28 to engage and return the sector 10 after a printing operation. A spring 30 connects an extension 31 of the sector 10 with a fixed part 32 whereby the spring 30 throws the sector to operative position when it is re leased. The details of the hammer release and restoring mechanism are referred to more or less generally because they are of the type shown in Patent No. 1,245,502, and have no specific bearing upon the present invention. That is to say, the sector invention herein described might be employed with various other hammer adjuncts and perform as satisfactorily as with those here shown by way of example.

The type 12 are mounted upon the sector 10 which is substantially of quadrant shape so that all of the type can be brought to proper printing position in accordance with the movement of the sector. In the present instance the type have alphabetical characters and the arrangement'of them is preferably a' group one rather than a consecutive one. Thus one group beginning with the letter A and ending with letter L comprises the even number type, while the other group from letter M to Z comprises the odd number type; for example, beginning with the free end of the sector, the second, fourth,

sixth, etc. type carry respectively the characters A, B, C, etc., while the first, third, fifth, etc. type carry respectively the characters M, N, O, etc.

For the purpose of locating the sector 10 so that the selected type is in printing position with respect to the platen 13, a plurality of stop pins 33 are provided and lo-' cated below but in the plane of movement of a stop lug 34 carried by the sector 10. In the present instance there are eleven pins 33 and one pivoted'shutter stop 35, the latter being normally engaged by the lug 34 to hold the sector 10 in its initial non-printing position. The pins 3.3 are raised into the path of the lug 34 by the action of an analyzing unit operating on a card perforated in a predetermined is shown-and described in U. S. Letters Patent N02 1,236,481 1- there is a lug46 In order to control the sector 10 for the two letter groups, the stop lug 34 projects from. a keeper 36 pivoted at 37 to the sector 10 and rovided with an offsetshoulder 38 arrange to be engaged by a heel latch 40. This latch 40 is pivoted at 41 to the heel of the sector and has stepped latch faces 42 and 43 for separately engaging the shoulder 38 according to whether one or the other face is in use as the retaining latch. The other end of the latch 40 is connected by a spring 44' with a hook extension 45 laterally pro'ecting from the keeper 36 so that the late 40 is yieldably held in latched position. At the opposite end of the keeper 36 which serves as a stop to limit themovement of the keeper by abutting a stop pin 47 on the fixed frame 48.

' With the shoulder 42'of the heel latch 40 in 7 db 40 an it engagement with the off-set shoulder 38' of the keeper 36 as shown in Fig. 1, the type sector will be held in its non-printing pos1- tion uponforward movement of the rod 28.

The two latch faces '42 and 43 are provided so that the sector 10 can have two fixed initial positions, one for each type group, changing from-one latch position to the ot er the group change can be made at will. Thus 'as shown the latch face 42 is. latched over thekeepershoulder 38 and the type sector in the initlal but non-printing position of-the group beginning with A, but

if thelateh face 43 is brought into operation the sector will be swung to a new initial position when rod 28 is moved forward and .t pe M will then be in printing position. 11 other words the distance between the latch face 42 and 43 is the same as the length of the are between two adjacent type; while the distance between the latch I der 38,

the adjacent pins 33, as well as the distance from the shutter 35 to the next adjacent pin 33 corresponds to the length of the are between eyery alternate type or adjacent type of the same group. Thus with the latehface 42 engaging the keeper shoulder 38, the operation of the stop pins 33 will result in the sector 10 taking positions cqrresponding to the type group beginning with the letter A, and with face 43 engaging the keeper shoulthe operation of the'stop pins 33 will 1 result in the sector 10 taking positions cor- .der' the p11 l of the responding to the type group beginning with the letter M.

i As a means for automatically changing from the group latch 42 to the group latch 43 according to requirements, 50 is provided having its upper end below and in close proximity to a part 51 of the the tension of the spring 44 'In operation of the control system it is evident that one group of type will require but a single perforation in its proper place onthe card 'to set up a selected typeywhile.

for a selected type in theother group, except the first one, card will be necessary and one of these is the same for each type. Thus as here shown a'card punched for the letter M in the location to operate the release latch 50 will cause such release latch 50 to change latch 40 from face 42 to face 43 andthereby permit the sector to swing the required distance to bring the M'type' into position. Since the shutter 35 remains stationary the lug 34 is not released and at the end of the cycle the restoring link 26 brings the sector heel back to relatch the shoulder 38 with the face 42. Now if type N is to'be set up the card will have the perforation necessary to opcrate release pin 50 plus a perforation in the location necessary 33 and as this latter is raised it'shiftsthe shutter 35 to release the lug 34 of the keeper 36. The pin 50 in the meantime has changed the latch 40 so that its face 43 will be in a position to cooperate with the shoulder 38 and conse uently when the sector swings unspring 30 until the lug 34' abuts the set p n printing 13. When a be brought to printing position but one perforation in the proper place in the card is necessary, and since the release pin 50 is not caused to function, control the position of the sector and allow it .to* bring alternate type to printing position.

It will now be apparent that a complete unitary sector for alphabetical printing has been devised wherein the number of parts usually believed necessary to carry out. th desired function has been materially reslngle integral element has been devised group beginning with M, will lift the the shoulder 38 will be engaged by two perforations 1n the to lift the first of the pinsthe N type will be'in position with respect to the platen letter of the other group is to the latch face 42 willa release pin duced, while in place of a multipart sector a and a cont ol therefor provided which is positive in action, rugged in construction and accurate in operation.
